A variable stator vane arrangement includes a casing, a plurality of stator vanes, at least one control ring, a plurality of connecting rods and a crankshaft. The stator vanes are circumferentially spaced apart in the casing and the plurality of stator vanes are rotatably mounted in the casing. Each control ring is rotatably mounted on the casing and each stator vane is connected to an associated control ring. The crankshaft, rotatably mounted on the casing, is drivingly connected to each control ring and has an axis and a plurality of clevizes. Each connecting rod connects one of the clevizes on the crankshaft to a respective one of the control rings. At least one clevis is adjustably secured to the crankshaft by an adjusting mechanism and the adjusting mechanism is used to select the radial and/or angular position of at least one clevis relative to the axis of the crankshaft.
